v0.1.0-alpha01 — first alpha (tester build)

First public alpha of OpenHearing — open-source hearing assistance for Android.

⚠️ Please read first

• Not a medical device. OpenHearing is a sound-amplification / hearing-assistance tool, not a certified hearing aid and not a substitute for a professional hearing exam. It does not diagnose or treat anything.
• Alpha quality — not yet validated on real hardware. The full pipeline is built and unit-tested, but the live audio path has not been verified on physical devices/earbuds yet. Treat this as a tester build. Use a headset, start quiet, keep the volume comfortable, and stop if anything is too loud.
• This is a signed release build (R8-optimized).

What it does

• Pure-tone hearing screening → a per-ear audiogram
• Builds an amplification profile (half-gain rule)
• Real-time hearing assist: multi-band gain + compression + feedback guard + a hard output limiter
• Comfort calibration, high-contrast theme, fully on-device (no accounts/ads/analytics/network)

Install

1. Download OpenHearing-0.1.0-alpha01.apk below.
2. On your Android phone (8.0+/API 26+), allow installing from your browser/files app.
3. Open it and install. Grant microphone access when you try Hearing assist.

Known limitations

• Live audio not yet device-validated (help wanted!).
• AirPods Pro 2/3 integration is not implemented yet (works with any earbuds).
• The screening is uncalibrated — results are estimates, not clinical values.

Help / feedback

Tester reports very welcome — especially anything clicky, distorted, or surprisingly loud (please report loudness/safety issues privately per SECURITY.md). See the README and device-testing guide.
